七、情态动词
-
He can be at home now because the light in his room is still on. 表特别有把握的肯定判断时用must,表特别有把握的否定判断时用can, can表判断时只用在否定句中。因此把can 改为must。
-
He need come here before the meeting begins. 作情态动词时need用在否定,疑问和条件句中,不能用于肯定句中,而作实意动词时则可以。所以应改为:He needs to come here before the meeting begins.
-
He used to get up very early in the morning, and now he is still doing so. used to 用来表示过去常常做某事而现在不了,所以应把后半句改为:but now he is not doing so.
-
I needn’t come yesterday because all the work had been finished. 由于情态动词本身不体现时态,所以在谈论过去的事情时在情态动词后加 have done,因此在 needn’t 后加have。
-
You hadn’t better stay up too late because you have to get up early tomorrow. had better 的否定在 better 后面加not.
八、动词的时态
英语的常用时态有十六种,一般根据上下文和时间状语来确定时态。
-
I will tell her about that when she will come tomorrow. 主句为将来时,其时间、条件、方式和让步状语从句中用一般现在时。因此将will come改为comes。
-
The meeting is about to begin in ten minutes. be about to 一般不与具体的时间状语连用。因此把 in ten minutes 去掉。
-
The boy opened his eyes for a moment, looking at the captain and then died. 此处look并非伴随状语,而是三个并列的谓语动词,因此把looking 改为looked。
-
I have bought this bike for ten years and I am still using it now. 当句中有for加一段时间作状语时,谓语动词必须为延续性动词,此处把bought改为kept。
-
I haven’t learnt any English before I came here. 我来这儿已经是过去的动作,在此之前发生的事应该用过去完成时。因此应把haven’t改为hadn’t
九、动词的语态
及物动词用在主动语态时要有宾语,因此可以变为被动语态;不及物动词用于主动语态时不能接宾语,因此无被动语态。
-
The two thieves have been disappeared. disappear 为不及物动词,因此不能用于被动语态。所以把 been去掉。
-
The building built now will be our teaching building. 表“现在正在建的”应用被动语态的正在进行时,因此在built 前加being。
-
He is being operated by the famous doctor. 主动语态变为被动语态时,应注意短语动词的完整性,别忘了介词或副词。“给…做手术”应为operate on sb,所以在operated 后加上on。
-
I wonder if the doctor has been sent. 原因同上,应在sent 后加上for。
-
The book written by him is sold well. 说一本书畅销是指书本身的属性,因此不用被动语态。本句应改为:The book written by him sells well.
-
This history book is worthy reading. “值得被做”可以有如下几种说法:be worth doing; be worthy of being done; be worthy to be done. 因此本句应该为:This history book is worthy to be read.
